I noticed this issue affects my system mentioned above under WinXP too. Even more with WinXP.
So I think this whole "bug" is hardware -related. This bug is not to blame Linux. I used WinXP to show animated movies to my kids as video quality is better with WinXP. Videos played without a glitch, but after that my wife surfed the internet using Firefox and XP, and black 1 second blinks appeared at approximately 5 minutes intervals. So, hardware related. I will come back to tell if this is a problem with DisplayPort as I imagine. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1011732 Title: External display blinks off periodically To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1011732/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
